Choosing the right roofing material for your shed can save you time, money, and hassle in the long run. When deciding between an EPDM rubber roof and a traditional felt roof, understanding the differences in lifespan, maintenance, weather resistance, and cost is crucial. This guide breaks down these factors to help you decide which option fits your needs best, especially if you are considering a shed roof upgrade.
Lifespan Comparison of Rubber Roof vs Felt Roof
One of the most significant differences between an EPDM shed roof and a felt roof is how long each lasts.
EPDM Rubber Roof
EPDM (ethylene propylene diene monomer) rubber roofs typically last 20 years or more. This durability comes from the material’s resistance to UV rays, ozone, and extreme weather conditions. Many manufacturers offer warranties ranging from 20 to 30 years, reflecting the confidence in EPDM’s longevity.
Felt Roof
Felt roofs generally last between 5 and 10 years. Felt is made from bitumen and reinforced with fibers, but it tends to degrade faster under harsh weather, especially in areas with heavy rain, snow, or intense sun. Over time, felt can crack, blister, or peel, requiring frequent repairs or replacement.
If you want a long-term solution with minimal worry, an EPDM shed roof offers a clear advantage.
Maintenance Needs for Each Roof Type
Maintenance plays a big role in the overall cost and effort of owning a shed roof.
EPDM Rubber Roof Maintenance
EPDM requires very little maintenance. It is resistant to cracking and shrinking, and its smooth surface prevents moss and algae growth. Occasional cleaning with water and mild detergent is usually enough. Inspections every few years to check for punctures or seam issues are recommended but rarely reveal major problems.
Felt Roof Maintenance
Felt roofs demand more attention. They can develop leaks, especially around seams and edges. Regular inspections are necessary to spot damage early. You may need to patch holes or reapply bitumen coatings every few years. Moss and algae growth can also be an issue, requiring cleaning or treatment.
For those who prefer a low-maintenance option, the EPDM shed roof is a better choice.
Weather Resistance and Performance
How well a roof handles weather impacts its lifespan and maintenance needs.
EPDM Rubber Roof Weather Resistance
EPDM excels in weather resistance. It handles temperature fluctuations without cracking and remains flexible in cold weather. Its waterproof nature prevents leaks, and it resists damage from UV rays and ozone exposure. This makes it ideal for regions with harsh winters or hot summers.
Felt Roof Weather Resistance
Felt roofs are more vulnerable to weather damage. They can become brittle in cold weather and soften in extreme heat, leading to cracks or blisters. Heavy rain can cause water to seep through if the felt is damaged or improperly installed. Felt also degrades faster under constant sun exposure.
If your shed is exposed to challenging weather, an EPDM rubber roof will provide stronger protection.
Cost Considerations for Rubber Roof vs Felt Roof
Cost is often a deciding factor when choosing roofing materials.
Initial Cost
Felt roofs are cheaper upfront. Materials and installation costs are lower, making felt a budget-friendly option for short-term use or smaller sheds.
Long-Term Cost
EPDM roofs cost more initially but save money over time. Their long lifespan and low maintenance reduce the need for repairs and replacements. When factoring in the cost of multiple felt roof replacements over 20 years, EPDM often proves more economical.
Shed Roof Upgrade Opportunity
Upgrading your shed roof to EPDM can increase the value and durability of your shed. It also reduces the hassle of frequent repairs, making it a smart investment for homeowners who want a reliable, long-lasting roof.
Practical Examples and Recommendations
If you have a small garden shed used occasionally, a felt roof might be sufficient and cost-effective.
For larger sheds or workshops where weather protection is critical, an EPDM shed roof is worth the investment.
In areas with extreme weather, EPDM’s durability and weather resistance make it the preferred choice.
If you plan to keep your shed for many years, a shed roof upgrade to EPDM will save you money and effort in the long run.
